If your value is based on the level of your pay, and you are paid peanuts, will you not behave like a monkey? What's the best way to get values-do we make them up as we go along? How about spending hours thinking up your own? Then there is the wisdom literature route-take values from a piece of religious writing and internalise them (the 'thou shalt not steal, thou shalt not commit adultery)-the catch is that you usually have to believe in the deity concerned.
Why bother with all this? The reason is that if you don't then you will value all things and actions as equal and respond to all situations with the same level of emotion. A current example-there iss a young man in the resaurant who has not caught the company value the 'the client is first'. As a result he will ignore any potential guest until his current job is done-be it washing the floor, drying glasses-he treats those with the same value as the person who pays the bill.
So what if you value family(all family even the ones you hate), work, cleanliness,maintenance, chores, the postman all the same, how will you prioritise...you get the picture!
